Yes the S works are very light with thin sidewalls. That does not bother me because I don't think I have ever torn a sidewall. At least not in recent memory. If you ride Whistler a lot I think that is a consideration. Lots of rough edged rocks there. North Shore, not so much. I ran S works Eskars a few years back. I loved the weight and size.

Continental has a light 2.4 Mountain King Protection series. I like those a lot.
